WIRE-SPLIGING TOOL OR WRENCH.

Application filed January 21, 1926.

The object of the invention is to provide a very simple and efficienttool for splicing wire.

Objects relating to details and economics of construction and operationof my invention will definitely appear from the detailed description tofollow.

The invention is defined and pointed out in the claim.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisapplication, in which:

Fig. 1 is a detail view of my improved wire splicing wrench or tool inuse, the tensioning means and wire clamp with which it is used beingshown in dotted lines;

Fig. 2 is a side elevation of my improved tool substantially full size,the ratchet teeth, pawl and spring being indicated by dotted lines;

Fig. 3 is a detail view of the head with one side removed, appearingsubstantially as a section on line 3-3 of Fig. 4, with the 25 twistinghead and the actuating dog and spring in full lines;

Fig. 4 is a sectional view taken on line H of Figs. 2 and 3;

Fig. 5 is a transverse detail sectionalview taken on line 5-5 of Figs. 3and 4, showing the pawl, spring, and retaining means;

Fig. 6 is a detail view of the meeting ends of the wire inserted intothe double tubular connector; and

Fig. 7 shows the same after it has been twisted by my improved wiresplicer and the splice completed.

The parts of the drawing will be referred to by their numbers, whichidentify like parts in all the views.

Referring to the drawing, 1 is the double handle made of symmetricalcorresponding plates, offset at 11, 11 into separated sides or cheekpieces 13, 13, which are adapted to embrace the hub of the revolvingwire twisting head, being radially open at 14 at the outer end. Theseplates are retained together by suitable rivets or screws 12, Betweenthese parts is retained the revolving twisting head 2 provided with ahub 21 on each side with peripherally projecting ratchet teeth 22. Aradial slot 23 extends Serial No. 82,706.

to the center where there is formed a seat 2 1 conformed to receive adouble tubular wire splice. brace the hubs and head so that it is heldunder slight friction and the handle can be readily revolved about it torotate the same for twisting the splice. v

A dog or pawl 8 is provided for this purpose which is pivoted on thecross pivot 31, provided with an engaging tooth 32 corresponding to theratchet teeth 22 on the head. A projecting thumb piece 33 at the side ofthe handle facilitates manipulation of the tool. A spring 1 with crosshead &1 engaged in apertures 42 in the cheek pieces 13 holds the dogyieldingly in engagement with the ratchet teeth.

The tool is a special tool for splicing. wire. The wires are tensionedby the usual puller devices, indicated by dotted lines in Fig. 1, andthe ends of the wire 5 are inserted in the tubular connector 6 and aregrasped by a wire clamp. My improved tool is then brought into action byslipping it over the wire and sliding it endwise onto the double wireconnector in proximity to the clamp. The tool is then rotated byoperating the handle ratchet-wise. l/Vhen the splice has been completedand the tool has The sides of the handle em 0 passed oil' from theconnector the dog 3 is depressed to free the head and the tool is pulledoil the wire, thus bringing the head with its radial slot to theprecisely correctposition in the cheek pieces for tuture use. The dog isreleased and the head is thus held so that there is no need foradjusting the twisting head in the tool.

I am aware that ratchet heads have been variously held for variouspurposes and I do not wish to be understood as claiming the samebroadly. I wish to claim the fea ture that cooperates with the connectorby sliding action.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

In a wire splicing tool or wrench for applying a splice sleeve connectorto wires,

the combination of a handle made up of symmetrical sides with headembracing portions open at the outer ends, a twisting head with hubsextendlng into said embracing portions provided with a ratchet at itsperiphery and a radial slot to cooperate with said open head embracingmeans, said slot being enlarged into engaging slots at its inner end toslide lengthwise of a connector sleeve a pawl or dog pivoted between thesides of said handle with alaterally for the de set ALBERT J.
